The Illawong Nature Reserve is on the South Coast of NSW, just west of The Bower at Broulee, 23 kilometres south of Batemans Bay (by road). The reserve has an area of 51 hectares (or about 130 acres).
The Reserve was dedicated in the 1960's as a refuge for waterfowl since it encompasses a part of the Illawong wetland and the greater wetland complex which forms part of the Candlagan Creek catchment. While much of this catchment has been cleared for cattle grazing, the wetlands themselves are fairly well preserved in a near natural state with complimentary neighboring land uses.
Candlagan creek itself has more recently been protected as an important fish breeding resource within the Batemans Marine Park.
